Shopify Plus Features: The Complete Guide for 2026

Most merchants who upgrade to Shopify Plus use less than 40 percent of what they are paying for. That is a five-figure annual gap between what the plan costs and the value teams actually extract, and it is almost always a knowledge problem rather than a platform limitation. This guide walks through the Shopify Plus features that matter, in the order you should actually implement them, so your migration or upgrade turns into revenue instead of a bigger invoice.

TL;DR

• What You Are Paying For: Shopify Plus features center on checkout customization, automation via Flow and Functions, B2B wholesale, multi-store management through Organization admin, and higher API limits. The starting price is roughly $2,300 per month on an annual contract, so the features need to pay for themselves within the first 60 to 90 days.
• Implementation Order Matters: The teams that win treat Plus as a phased rollout, foundation first (checkout, scripts to Functions, Flow), then B2B and expansion stores. At Presta, we’ve seen rushed all-at-once launches burn 3 to 4 extra weeks in rework.
• Measure Or Lose It: Set 30/60/90 day KPIs before you touch a single setting. Without baseline conversion and operational-hours numbers, you cannot prove the upgrade paid off, and roughly 1 in 3 merchants we audit cannot.

Step 1: Confirm Shopify Plus Is the Right Tier Before You Touch a Feature

Before you get excited about checkout branding or automation, confirm you belong on Plus at all. This is the single most expensive decision in the entire process, and we see merchants get it wrong in both directions: some scale on the standard Advanced plan long past the point of pain, and others jump to Plus for features they will never use.

The rough financial threshold is straightforward. The standard Advanced plan runs about $399 per month. Shopify Plus starts around $2,300 per month on annual terms, or a revenue-share model of 0.25 percent of monthly revenue (capped at $40,000 per month) once you cross into the eight-figure range. That is a jump of roughly $1,900 per month, or about $22,800 per year. To justify it, the Plus-only features need to generate or save at least that much.

When does the math actually work?

In our experience, the tipping point lands in one of three places. First, when your monthly revenue crosses roughly $800,000 to $1,000,000 and the 2 percent third-party transaction fees on non-Shopify-Payments gateways start eating real margin. Second, when your operations team is manually doing work that Flow and Functions could automate, and that manual labor exceeds about 15 to 20 hours per week. Third, when you need checkout customization, B2B, or multiple regional storefronts that the standard plans simply do not permit.

If you are still weighing platforms entirely, our WooCommerce vs Shopify 2025 comparison breaks down where each platform stops scaling, and 7 reasons to switch from WooCommerce to Shopify covers the operational triggers that push teams to migrate in the first place.

What features are Plus-exclusive versus available lower down?

This confuses almost everyone, because Shopify has quietly moved several formerly-Plus features down the ladder. Here is where things stand for 2026.

Feature	Standard Plans	Shopify Plus
Shopify Functions (custom logic)	Limited	Full access, higher limits
Checkout Extensibility	Basic	Full, including checkout.liquid successor UI
Shopify Flow automation	Available	Available, more connectors
B2B / Wholesale native	No	Yes
Expansion stores (multi-store)	No	Up to 10 included
Organization admin	No	Yes
API call limits	Standard bucket	2x to 8x higher throughput
Dedicated launch manager	No	Yes
Customer accounts (new)	Yes	Yes

Pro Tip: Do not upgrade to Plus purely for checkout branding anymore. Checkout Extensibility apps deliver most of the visual customization on lower tiers now. Upgrade for the combination of B2B, expansion stores, higher API limits, and Functions throughput, not for a single feature you can approximate cheaper.

At Presta, when we scope this for clients, we run a simple one-page cost-versus-value model before anyone signs the annual contract. If the projected savings and revenue lift do not clear the $22,800 annual delta with at least 30 percent headroom, we tell them to wait. That candor has saved clients real money and kept us out of upgrades that would have quietly failed.

Checkpoint: You have confirmed Plus is right when you can point to at least two concrete, quantified reasons (revenue threshold crossed, transaction-fee savings, or a specific Plus-only capability you need) that together exceed the annual cost delta.

• Revenue Check: Confirm monthly revenue is trending past $800K, or that a specific Plus-only feature is a hard requirement.
• Fee Audit: Calculate current third-party transaction fees and whether Shopify Payments eliminates them.
• Ops Audit: Log manual hours per week that Flow or Functions could automate.
• Feature Match: List which capabilities you need are genuinely Plus-exclusive versus available cheaper.
• Contract Terms: Compare the flat monthly rate against the revenue-share model at your volume.
• Headroom Rule: Require projected value to beat the cost delta by 30 percent before committing.

Step 2: Map Your Feature Rollout in Phases, Not All at Once

The fastest way to waste your first 90 days on Plus is to try to activate everything simultaneously. Checkout customization, Flow automations, Functions, B2B, and expansion stores each carry their own testing and QA overhead, and stacking them creates a debugging nightmare where you cannot isolate what broke.

Our Startup Studio team frequently builds Plus rollouts in three clean phases, and this sequencing alone typically shaves 3 to 4 weeks off a launch compared to the “flip every switch” approach.

The FOUNDATION-FIRST Framework

We use a named framework internally called FOUNDATION-FIRST because the order is the whole point. It has three phases.

Phase One, Foundation (Weeks 1 to 3): Migrate checkout to Checkout Extensibility, convert any legacy Scripts to Functions, and stand up your first 3 to 5 Flow automations for the highest-volume manual tasks. This phase directly protects conversion and cuts labor immediately.

Phase Two, Revenue Expansion (Weeks 4 to 7): Launch B2B if you sell wholesale, then configure expansion stores for new regions or brands. This phase opens new revenue lines rather than optimizing existing ones.

Phase Three, Optimization (Weeks 8 to 12): Layer advanced Flow logic, custom Functions for discounts and shipping, and API integrations with your ERP, PIM, or 3PL. This phase compounds the value of everything below it.

Phase	Timeframe	Effort	Expected Outcome
Foundation	Weeks 1-3	High	Checkout live, 15-20 manual hours/week reclaimed
Revenue Expansion	Weeks 4-7	Medium-High	B2B channel live, 1-3 new regional stores
Optimization	Weeks 8-12	Medium	Custom logic deployed, ERP/3PL synced

Why not just do it all in week one?

Because every feature you activate becomes a variable when something goes wrong, and on a live store handling real orders, “something goes wrong” is a matter of when, not if. When we scope this for clients, we insist on a rollback plan for each phase and a two-week stabilization window after Foundation before touching B2B. Merchants who skip that window see roughly 2x the post-launch support tickets in their first month.

If you are migrating from WooCommerce as part of this move, our guide on how to migrate from WooCommerce to Shopify in 2025 and the deeper piece on turning WooCommerce to Shopify transitions into growth stories both explain how to sequence data migration alongside feature rollout without stepping on your own launch.

Checkpoint: You have a phased plan when you can show a three-column roadmap that assigns every Plus feature to a specific phase, with a named owner and a rollback step for Phase One.

• Phase Assignment: Slot every feature into Foundation, Revenue Expansion, or Optimization.
• Owner Per Task: Assign a single named person to each feature, not a team.
• Rollback Plan: Document how to revert checkout and Flow changes if conversion drops.
• Stabilization Window: Block two weeks between Foundation and Phase Two.
• Dependency Check: Confirm no Phase Two feature secretly depends on unfinished Phase One work.
• QA Gate: Define pass criteria before each phase is allowed to start.

Step 3: Deploy Checkout Extensibility, the Highest-Leverage Plus Feature

Checkout is where money changes hands, so it is where Plus earns its keep first. Shopify has fully retired the old checkout.liquid customization model, and Checkout Extensibility is now the supported path. This matters: merchants still running on the deprecated checkout.liquid are on borrowed time, and migrating that is often the real reason a team needs Plus-level support.

Checkout Extensibility lets you customize the one-page checkout, thank-you page, and order-status page using app blocks and UI extensions rather than fragile Liquid overrides. For a Plus merchant, this unlocks branded checkout, custom fields, upsells, address validation, and conditional content, all without the maintenance risk of the old approach.

What conversion levers actually live in checkout?

The highest-impact ones, in the order we typically deploy them:

1. Trust and branding: Logo, colors, and typography that match the storefront. This alone reduces checkout abandonment by a few percentage points because the transition no longer feels jarring.
2. One-page checkout: Now the default, but confirm your extensions do not accidentally reintroduce steps.
3. Post-purchase upsells: A one-click upsell on the thank-you page routinely lifts average order value by 5 to 12 percent with zero added friction to the initial purchase.
4. Custom fields and validation: Capture delivery instructions, gift messages, or B2B PO numbers, and validate addresses to cut failed-delivery costs.
5. Conditional shipping and payment logic: Hide payment methods or shipping rates based on cart contents or customer segment.

Pro Tip: Deploy post-purchase upsells before you touch branding. The revenue impact is measurable within days, which gives you an early, quantified win to justify the entire Plus upgrade to whoever signs the checks. We have watched a single well-targeted post-purchase offer pay for a month of the Plus subscription on its own.

At Presta, we treat checkout as a testing surface, not a set-and-forget config. We baseline conversion for two weeks, ship one change at a time, and measure. That discipline is why our checkout work reliably moves the number instead of just looking prettier.

Checkpoint: Checkout is deployed correctly when your live checkout matches brand guidelines, passes a full test order end to end, and at least one measurable conversion lever (upsell or reduced steps) is live and being tracked.

• Migration Off Legacy: Confirm you are on Checkout Extensibility, not deprecated checkout.liquid.
• Brand Match: Verify logo, colors, and fonts render across desktop and mobile.
• Upsell Live: Ship at least one post-purchase upsell and track AOV impact.
• Field Validation: Add and test any custom fields and address validation.
• Test Order: Run a full end-to-end purchase including refund and order-status views.
• Baseline Set: Record pre-change conversion so you can prove the lift.

Step 4: Automate Operations With Shopify Flow and Functions

This is where Plus quietly saves the most money, and where most merchants leave the most on the table. Flow and Functions turn repetitive human tasks into backend logic, and for a team drowning in manual order tagging, fraud review, and inventory alerts, this is often worth more than any checkout tweak.

What is the difference between Flow and Functions?

They solve different problems, and conflating them causes bad architecture decisions.

Shopify Flow is a visual, no-code automation builder. It works on triggers, conditions, and actions: when an order is placed (trigger), if it is over $500 (condition), then tag it and notify the fraud team (action). Flow is for workflows and business logic that a non-developer should be able to read and edit.

Shopify Functions is code-level customization that runs on Shopify’s servers, replacing the old Scripts. Functions handle discounts, shipping and payment method logic, cart validation, and bundling. This is developer territory, and it is where you build the custom pricing and promotion logic that used to require janky workarounds.

Capability	Shopify Flow	Shopify Functions
Skill needed	No-code / ops team	Developer
Best for	Workflows, tagging, notifications	Discounts, shipping, cart logic
Runs where	Backend event triggers	Checkout and cart runtime
Editable by	Non-technical staff	Engineering only
Typical time to build	15-60 minutes each	1-5 days each

Which automations should you build first?

Start with the workflows that eat the most human hours. In our audits, these five almost always top the list:

1. High-value order tagging and fraud routing (saves 2 to 4 hours/week).
2. Automatic inventory-low alerts to purchasing (prevents stockouts worth thousands per incident).
3. Customer segmentation and tagging based on order history and value.
4. Automated refund and return workflows for standard cases.
5. VIP or wholesale customer flagging and tier assignment.

The real ROI of Shopify Plus features is not a prettier checkout, it is the 15 to 20 hours a week your team stops spending on work a machine should do.

At Presta, we’ve seen a mid-size Plus merchant reclaim roughly 18 hours per week across their operations team within the first month just by automating order tagging, fraud routing, and inventory alerts. At a blended ops cost of around $35 per hour, that is close to $32,000 per year recovered from three afternoons of automation setup.

Checkpoint: Automation is working when at least three Flow workflows are live in production, each is logging successful runs in the Flow activity feed, and you can name the specific manual task each one eliminated.

• Task Inventory: List every recurring manual task and its weekly hours.
• Flow Vs Functions: Correctly assign each need to no-code Flow or coded Functions.
• Top Five Live: Build the five highest-hour automations first.
• Run Logging: Confirm each workflow logs successful executions.
• Failure Alerts: Add a notification for any Flow that errors out.
• Hours Reclaimed: Quantify weekly hours saved and translate to dollars.

Turn Your Plus Upgrade Into Measurable Growth With Presta

Activating Shopify Plus features is straightforward on paper and treacherous in practice, because the sequencing, QA, and measurement discipline are what separate a five-figure win from a five-figure wasted subscription. Our Startup Studio has run this exact playbook for merchants scaling past eight figures, and we build the checkout, Flow, Functions, and B2B architecture so it pays for itself inside the first quarter. If you want a partner who treats your Plus upgrade like a P&L line and not a checklist, hire Presta’s Startup Studio to launch and scale or talk to our team directly about scoping your rollout.

Step 5: Configure B2B and Wholesale as a Native Revenue Channel

For merchants who sell to other businesses, native B2B is one of the most underused Shopify Plus features, and one of the fastest to pay back. Shopify Plus builds B2B directly into the platform now, replacing the old separate wholesale channel, so you manage company accounts, price lists, payment terms, and quantity rules from the same admin as your DTC store.

What does native B2B actually give you?

The core capabilities that matter for revenue:

1. Company profiles with multiple buyers, each with their own permissions and locations.
2. Customer-specific catalogs and price lists, so different accounts see different pricing.
3. Net payment terms (Net 15, Net 30, Net 60) with tracked balances.
4. Quantity rules and volume pricing enforced at the cart level via Functions.
5. Self-serve reordering, which cuts the phone-and-email order-taking that clogs sales teams.

The operational win here is significant. When we scope this for clients, B2B buyers who can self-serve reorder typically place orders 30 to 40 percent more frequently than those who have to email a rep, simply because friction drops. And your sales team stops being a human order-entry system.

Pro Tip: Do not run separate DTC and B2B stores unless you genuinely have separate brands or fulfillment. Native B2B on a single store shares inventory, customers, and reporting, which eliminates the reconciliation headache of two-store setups. We only recommend a separate expansion store for B2B when the catalogs, currencies, or fulfillment are fundamentally different.

How does B2B connect to expansion stores?

If you sell wholesale into multiple regions, expansion stores (Plus includes up to 10) let you spin up region-specific storefronts with local currency, language, and tax handling, all governed from the Organization admin. This is where the multi-store architecture of Plus starts compounding, and it is a big part of why we describe Shopify as more than just a platform for the next decade.

Checkpoint: B2B is configured correctly when at least one company account can log in, see its custom price list, place a self-serve order with the correct payment terms, and that order flows into your normal fulfillment without manual intervention.

• Company Setup: Create company profiles with buyers and locations.
• Price Lists: Build customer-specific catalogs and volume pricing.
• Payment Terms: Configure and test Net terms with balance tracking.
• Quantity Rules: Enforce minimums and increments via Functions.
• Self-Serve Test: Confirm a buyer can reorder without contacting sales.
• Fulfillment Flow: Verify B2B orders route into standard fulfillment.

Step 6: Manage Scale With Organization Admin and Higher API Limits

Once you are running multiple stores or high order volume, the plumbing matters as much as the storefront. Two Shopify Plus features handle this: the Organization admin and dramatically higher API limits.

What does Organization admin solve?

Organization admin is the control layer above individual stores. It gives you centralized user management, single sign-on, store-level permissions, and consolidated analytics across all your storefronts. For a brand running a DTC store, a B2B store, and three regional expansion stores, this is the difference between managing one system and managing five disconnected ones.

The practical value: onboarding and offboarding staff across all stores from one place, enforcing security policy centrally, and getting a roll-up view of performance without exporting five separate reports. For teams past about 15 staff or 3 stores, this saves several hours per week of admin overhead and closes real security gaps.

Why do higher API limits change what is possible?

Standard Shopify plans cap API throughput, which becomes a hard ceiling when you integrate an ERP, PIM, 3PL, or custom middleware. Plus raises those limits substantially, in some cases 2x to 8x depending on the API and endpoint, which means your integrations can sync in near real time instead of batching and lagging.

This is not abstract. A merchant syncing inventory across five stores and a warehouse system needs the throughput to keep stock accurate, and inaccurate stock causes oversells, cancellations, and refunds that erode both margin and trust. At Presta, we’ve seen higher API limits cut inventory sync lag from 15 to 20 minutes down to near real time, which measurably reduces oversell incidents on fast-moving SKUs.

Integration	Standard Plan Risk	Plus With Higher Limits
ERP inventory sync	Batched, 15-20 min lag	Near real-time
PIM product updates	Throttled at scale	Bulk operations supported
3PL order routing	Queued during spikes	Handles peak throughput
Custom middleware	Rate-limit errors	Headroom for growth

Checkpoint: Your scale layer is working when all stores are visible under one Organization admin, staff are provisioned centrally with SSO, and your core integrations sync without hitting rate-limit errors during a peak-traffic test.

• Central Users: Provision and deprovision staff from Organization admin.
• SSO Enabled: Turn on single sign-on and enforce it.
• Store Roll-Up: Confirm consolidated analytics across all storefronts.
• API Audit: Identify which integrations were hitting rate limits before.
• Throughput Test: Run a peak-load sync test and check for errors.
• Real-Time Inventory: Verify stock syncs fast enough to prevent oversells.

Step 7: Measure Success With 30/60/90 Day KPIs

Everything above is theater if you cannot prove it worked. This step is non-negotiable, and it is the one merchants skip most often. Before you activated a single feature in Step 1, you should have captured baselines. Now you measure against them.

What should you measure at each interval?

We hold clients to a strict 30/60/90 cadence, because Plus value shows up on different timelines. Checkout and automation pay back fast; B2B and expansion stores compound over months.

Timeframe	Primary KPIs	Target Signal
30 Days	Checkout conversion, AOV, ops hours reclaimed	Conversion flat-to-up, 10-18 hrs/week saved
60 Days	B2B orders placed, upsell attach rate, sync error rate	First B2B revenue, upsell attach 8-15%
90 Days	Total revenue lift, transaction-fee savings, subscription ROI	Plus paying for itself with 30%+ headroom

At 30 days, the story is operational: is the team spending fewer hours on manual work, and did checkout conversion hold or improve? At 60 days, revenue channels should be showing signs of life, B2B orders flowing and upsells attaching. At 90 days, you should be able to draw a clean line from the Plus subscription cost to the value it generated, and that line should clear the cost with the 30 percent headroom we required back in Step 1.

How do you attribute the wins honestly?

Do not credit Plus for revenue it did not cause. Use the baselines. If checkout conversion was 2.8 percent before and 3.1 percent after with no other major change, that delta is attributable. If ops hours dropped from 40 to 22 per week, that is a hard, defensible saving. We build a simple one-page scorecard for clients that puts cost on one side and quantified value on the other, and we review it at each interval. If the numbers do not clear, we adjust the feature mix instead of pretending.

If you would rather have this scale handled for you, our Shopify Plus agency service covers builds, upgrades, and B2B rollouts end to end. For a broader view of what agency-led Shopify work should produce, our breakdown of what it looks like to hire a Shopify agency for results sets the expectation that every engagement ties back to measurable outcomes, not activity.

Checkpoint: Your measurement is working when you have a single scorecard showing baseline versus current numbers for at least five KPIs, and you can state in one sentence whether Plus has paid for itself yet.

• Baselines Locked: Confirm you captured pre-upgrade conversion, AOV, and ops hours.
• 30-Day Ops Review: Measure hours reclaimed and checkout conversion.
• 60-Day Revenue Review: Track B2B orders and upsell attach rate.
• 90-Day ROI Review: Compare total value against subscription cost.
• Honest Attribution: Credit only deltas Plus actually caused.
• Decision Point: Decide whether to expand, hold, or adjust the feature mix.

Common Mistakes That Kill Shopify Plus ROI

Mistake: Activating every feature in the first week. Why It Happens: Excitement about the new capabilities and pressure to justify the cost fast. Fix: Follow the FOUNDATION-FIRST phasing so you can isolate what works and roll back what breaks.

Mistake: Upgrading to Plus purely for checkout branding. Why It Happens: Checkout customization is the most visible feature, so it gets overweighted in the decision. Fix: Justify the upgrade on the full stack (B2B, expansion stores, Functions throughput, API limits), not one cosmetic feature you can approximate on cheaper tiers.

Mistake: Never measuring against a baseline. Why It Happens: Teams get busy launching and forget to capture pre-upgrade numbers, then cannot prove ROI later. Fix: Lock in baseline conversion, AOV, and ops hours before Step 1, and review them on the 30/60/90 cadence.

Advanced Tips for Getting More From Shopify Plus

Once the foundation is solid, a handful of advanced moves separate merchants who merely use Plus from those who compound its value.

Chain Flow with Functions for dynamic promotions. Use Flow to detect a customer segment or behavior, then trigger Functions-based discount logic at checkout. This lets you run personalized, rules-driven promotions that would be impossible with static discount codes, and it is one of the most powerful and least-used Shopify Plus automation features. We have used this pattern to run automatic tiered loyalty pricing that lifted repeat-purchase revenue by double digits.

Use expansion stores as testing sandboxes. Spin up a low-traffic expansion store to test theme changes, checkout experiments, or new apps before deploying to your primary storefront. This gives you a production-like environment without risking your main revenue. Our complete guide to Shopify store redesign, agency versus DIY goes deeper on staging strategy for larger visual changes.

Automate B2B onboarding end to end. Combine Flow, company profiles, and price lists so a new wholesale account is provisioned, tagged, assigned to the right price list, and sent a welcome sequence automatically. This turns wholesale onboarding from a multi-day manual process into a same-hour one, and it scales without adding sales headcount.

Instrument everything with metafields and tags. The merchants who get the most from Plus treat data as a first-class citizen: consistent tagging and metafield structures make every future automation, integration, and report easier to build. Sloppy data early becomes technical debt that slows every later project.

• Flow Plus Functions: Chain segment detection with runtime discount logic.
• Sandbox Store: Test changes on an expansion store before production.
• B2B Automation: Fully automate wholesale account onboarding.
• Data Hygiene: Standardize tags and metafields from day one.
• App Discipline: Audit apps quarterly to remove ones Functions can replace.

If you are just getting started with Shopify Plus, prioritize Step 1 and Step 3 above all: confirm the tier is right, then get checkout deployed correctly on Checkout Extensibility, because that protects your revenue and gives you your first measurable win. If instead you are auditing an existing Plus store that already feels underused, start with Step 4 and Step 7: run the automation audit to find reclaimable hours, and build the scorecard so you can finally see whether you are getting your money’s worth. Most underperforming Plus stores we audit are leaking value in exactly those two places.

Next Steps:

• Run The Tier Math: Build the one-page cost-versus-value model from Step 1 this week.
• Audit Manual Hours: Log every recurring manual task and its weekly hours to size your automation opportunity.
• Set Baselines: Capture current checkout conversion, AOV, and ops hours before changing anything.

Frequently Asked Questions

What are the main Shopify Plus features?

The main Shopify Plus features cluster into five groups. Checkout Extensibility lets you fully customize and brand the checkout, thank-you, and order-status pages without the fragility of the old checkout.liquid model. Automation through Shopify Flow and Shopify Functions replaces manual operational work and custom-codes discount, shipping, and cart logic at the platform level.

The remaining three groups are about scale and commercial reach. Native B2B builds wholesale directly into the platform with company accounts, custom price lists, and payment terms. Expansion stores give you up to 10 storefronts for different regions or brands, governed centrally through the Organization admin. And significantly higher API limits let your ERP, PIM, and 3PL integrations sync in near real time.

The practical takeaway is that no single feature justifies the roughly $2,300 per month cost. The value comes from combining several of them against your specific business, which is exactly why Step 1 of this guide is about confirming the tier fits before you touch anything.

What are the most useful Shopify Plus advanced features?

The advanced features that deliver the most for scaling merchants are Shopify Functions and the multi-store architecture. Functions is the successor to Scripts and runs custom logic on Shopify’s own infrastructure, which means you can build sophisticated discounting, bundling, and shipping rules that used to require brittle workarounds or expensive apps.

On the scale side, the combination of expansion stores and Organization admin is what lets a brand operate as one business across many storefronts and regions. You get centralized user management, single sign-on, and consolidated analytics, which for a team running three or more stores eliminates hours of reconciliation and closes security gaps that come with managing separate admins.

We would also put chained Flow-and-Functions automations in the advanced category. Detecting a customer segment with Flow and then applying dynamic pricing through Functions at checkout is one of the highest-leverage patterns on the platform, and very few merchants use it well.

What are the best Shopify Plus automation features?

The best Shopify Plus automation features are Flow and Functions, and they are complementary rather than competing. Flow is the no-code, trigger-condition-action builder that your operations team can own directly, ideal for order tagging, fraud routing, inventory alerts, customer segmentation, and return workflows. It requires no engineering time and each workflow takes 15 to 60 minutes to build.

Functions is the code-level layer for anything that needs to run inside the cart or checkout, such as custom discounts, volume pricing, shipping method logic, and cart validation. It requires developers and each Function takes one to five days to build, but it unlocks pricing and promotion logic that is impossible with static discount codes.

In our audits, automating the five highest-volume manual tasks (high-value order tagging, inventory alerts, segmentation, returns, and VIP flagging) reliably reclaims 15 to 20 hours per week. At a blended ops cost around $35 per hour, that is roughly $27,000 to $36,000 a year recovered, which by itself often justifies the Plus subscription.

How much does Shopify Plus cost and is it worth it?

Shopify Plus starts around $2,300 per month on an annual contract, or a revenue-share model of 0.25 percent of monthly revenue capped at $40,000 per month once you are at very high volume. Compared to the standard Advanced plan at about $399 per month, that is a delta of roughly $22,800 per year that the Plus features need to earn back.

Whether it is worth it comes down to three tests we cover in Step 1: are you crossing roughly $800,000 to $1,000,000 in monthly revenue where transaction fees and scale pain appear, are you spending 15 or more manual hours a week on work automation could handle, and do you need a genuinely Plus-exclusive capability like B2B or expansion stores. If two of those are true, the math usually works with room to spare.

If only one is true, and especially if it is only “we want nicer checkout branding,” we generally advise waiting, because Checkout Extensibility apps deliver much of that on cheaper tiers now. Being honest about this threshold has saved our clients from upgrades that would have quietly underperformed.

When does it make sense to bring in Presta’s Startup Studio for a Shopify Plus rollout?

Candidly, not every merchant needs an agency for this. If you have a capable in-house developer, an operations lead who understands your workflows, and the bandwidth to run a phased rollout over 8 to 12 weeks, you can absolutely execute a solid Plus setup yourself using the sequencing in this guide. Plenty of teams do.

The threshold where it becomes worth bringing us in is usually one of three situations. First, when you are migrating from another platform (WooCommerce, Magento, or a legacy build) at the same time as adopting Plus, because the data migration and feature rollout have to be choreographed carefully to avoid launch disasters. Second, when you need custom Functions and complex B2B or multi-store architecture that your team has not built before, where a wrong architectural decision early costs weeks to unwind. Third, when the opportunity cost of your team’s time is high enough that paying specialists to compress a 12-week rollout into a tighter, lower-risk timeline simply pays for itself.

At Presta, our Startup Studio has run this playbook repeatedly for scaling merchants, and we scope every engagement against the same cost-versus-value discipline we recommend you use internally. If you want to sanity-check whether your situation clears that threshold, our guide on how to evaluate a Shopify migration agency is a good starting point, or you can talk to us directly.

Can I customize Shopify Plus checkout the way I could with checkout.liquid?

You can achieve most of what checkout.liquid allowed, and more, but the method is entirely different. Shopify has retired checkout.liquid customization, and Checkout Extensibility is the supported replacement. Instead of editing a Liquid template directly, you use app blocks and UI extensions to add branding, custom fields, upsells, and conditional logic.

The upside is durability. Checkout.liquid customizations frequently broke during platform updates and required ongoing maintenance. Extensibility-based customizations are built on supported APIs, so they survive updates far better and carry much lower long-term maintenance risk. For most merchants, the visible result is equal or better, with dramatically less fragility.

If you are still running on deprecated checkout.liquid, migrating it should be a top priority, and it is often the specific reason a team seeks Plus-level support in the first place. We treat that migration as part of the Foundation phase in Step 3.

Do I need multiple stores, or can I run everything on one Shopify Plus store?

You can and usually should run as much as possible on a single store. Native B2B lets you serve both DTC and wholesale customers from one storefront with shared inventory, customers, and reporting, which eliminates the reconciliation overhead of a two-store setup. For most merchants, one store handling both audiences is the right architecture.

You only need expansion stores when the differences are fundamental: separate brands, distinct catalogs, different currencies and tax regimes, or region-specific fulfillment that cannot be handled with markets and localization on a single store. Plus includes up to 10 expansion stores precisely for these genuine multi-brand or multi-region situations.

Our general rule when we scope this for clients is to default to a single store and only add expansion stores when there is a clear, quantified reason the added complexity is worth it. Every extra store is another surface to maintain, test, and secure.

How long does it take to fully implement Shopify Plus features?

A disciplined, phased rollout using the FOUNDATION-FIRST framework typically runs 8 to 12 weeks. Foundation (checkout, Scripts-to-Functions, initial Flow automations) takes about three weeks, revenue expansion (B2B and any expansion stores) takes another three to four weeks, and optimization (advanced Functions, complex Flow logic, ERP and 3PL integrations) fills weeks eight through twelve.

Trying to compress this into a single burst is the most common way teams waste their first quarter on Plus, because stacking every feature at once makes debugging nearly impossible and typically doubles post-launch support tickets. We build in a two-week stabilization window after Foundation for exactly this reason.

If you are also migrating from another platform simultaneously, add time for data migration and validation. Our resources on migrating from WooCommerce to Shopify and the broader Shopify agency services guide explain how to sequence migration and feature rollout so they reinforce rather than collide with each other.
